LOOM TEMPLE.

Application filed .Tuly 9, 1926. Serial No. 121,360.

invention relates to a. loom temple guided by a holder fixed to the breast beam of a loom, the temple being movable in one direction by a loom lay, and in the opposite direction by a spring associated with the holder.

The invention is embodied in certain improvements hereinafter described and claimed, having for their objects increased durability of the temple and holder, and convenient removability of the parts thereof, which are subjected to maximum wear.

Of the accompanying drawings forming a part of this specilieation,-

Figure 1 shows in transverse section a portion of a breastl beam and a temple and its holder, embodying my improvements, the holder being supported by the breast beam.

Figure 2 is a top plan view of the same.

Figure 3 is a4 ection on line 3 3 of Figure 2.

Figure a is an end view, the breast beam being omitted.

Figure 5 is a perspective view of the bushing hereinafter described.

The same reference characters indicate the same parts in all of the figures.

In the drawings, 12 designates the breast beam of a loom, and 13 ldesignates one of the selvage edges of a web of cloth. The temple which guides and engages the selvage edge, includes a base portion 111, a top portion 15, proximate surfaces of these portions forming a slot 16, through which the selvage edge passes, and a loose spurred roll or rolls 17, two being shown in this instance. The cloth is engaged as usual by the spurs of the rolls 17, while passing between the rolls and the top portion 15.

rhe base portion 111 is provided with an upstanding vertically elongated ear 18, cast integral therewith. To said ear is detachably fixed a shank 19, a reduced end portion of the shank being inserted in an orifice in the ear and secured by a clamping nut 20. To the outer portion of the ear 18 is simi larly fixed by a nut 20, a steady-pin 21, extending parallel with the sha-nk and spaced therefrom.

The temple is supported and guided by a holder, preferably including a body portion 22, adapted to be seated on the breast beam 12, and having a slotted flange 23, se-

cured to the breast beam by screws 24, passing through the flange slot. The body portion is longitudinally apertured to provide an internal bearing for the shank 19, said bearing, in this instance, including an inner portion formed by a bushing 25, and an outer portion 26, formed in one end of the body.

A spring 27, seated at one end on an abutment 28 in the body 22, and at its other end on a shoulder 29 on the shank, normally the breast beam. rI he temple is provided, as usual, with a lug 30, projecting into the path of the lay, which in advancing, moves the temple from the full line to the dotted line position in Figure 3, the spring moving the templeinthe opposite direction when the lay recedes. A stop nut 31, fixed to the shank, limits the movement of the temple by the spring.

The holder body 22 is provided with an upstanding ear 32, having an internal guise 33, in which the steady-pin 21 is slidable. rjfhe steady-pin and the ear 32 prevent lateral movements or vibrations of the shank 19 in its bearing, and reduce to a minimum the wear of the contacting` surfaces of the shank and the bearing usually caused by the operation of the loom, so that the durability of the attachment formed by the temple and holder is materially increased. rFhe greatest wear is sustained by that portion of the shank bearing formed by the bushing 25. The bushing is externally threaded and engaged with an internal thread formed in the body of the holder, so that in case it becomes objectionably worn, it may be removed and replaced by another, one end of the bushing being provided with faces 36 adapted to be engaged by a wrench.

The detachable connection of the shank and steady-pin with the ear 18 enables either part to be removed and replaced by a new part. It will be seen, therefore, that the attachment composed of the temple and holder, has a considerable number of units, each of which is removable and renewable, so that various repairs required by breakage or wear, may be inexpensively made by replacing minor parts. The steady-pin 21 is provided with a peripheral groove 37, adapted to be engaged by a latch 38 ,pivotpresses the shank and the temple away from 'With a shank guide in which ed at 39 to the ear 32, when the temple isvat the eXtreme of the movement imparted to it by the lay7 so that the temple may be locked in the position indicated by dotted lines in Figure 8, against movement by the web and provided with a. loose spurred Webengaging roll, an npetanding ear, a shank7 and a steady-pin, Said shank and pin being attached in spaced apart relation to the ear, and a temple holder adapted to be attached to the breast beam of a loom and provided the shank is movable, a spring in said guide, and an upstanding ear having a gni de in which the steady-pin is movable, the temple being movable in one direction by the loom lay, and in the opposite direction by the spring,

the steady-pin *and its guide preventing lateral movements of the shank and minimizing Wear of the contacting surfaces of the shank and its guide.
